Patent DE-2137103-A1 (DE)
Title: Double walled thermoplast shell - formed from hollow rough inclosing mould
Inventor: TERAOKA SHYOICHI
IPC: B29C49/48
Filed: 1971-07-24
Abstract: A method of making double-walled shell-type thermoplastic articles introduces a rough from an extruder nozzle into the space between the parts of an open mould; the rough first enters between positive and negative mould parts defining the shell shape, then an initial closure piece (or sleeve) slides on one part to bridge the gap across to the other part. This seals the mould and the positive and negative parts are brought together, the gas pressure inside the rough being maintained, so that the final thin double-walled shell is produced. Typical uses include double-walled boat hulls or baths.

Title: Increasing electrical strength of polymers - by incorporating additional scatter centres or reducing crystallinity
Inventor: BOETTGER OTTO PROF DR
IPC: H01B3/44
Filed: 1971-09-24
Abstract: The electrical breakdown strength of polymers esp. polyethylene, is increased by modifying the free path length of the charge carriers (electrons), (A) by incorporating additional scatter centres or (B) by reducing the crystallinity of the polymer. (A) is pref. achieved by introducing different atoms into the polymer chains, increasing the amount of branching in the chains, incorporating different atoms which are not chemically bound to the polymer e.g. additives during extrusion or by diffusion, or by addition of fillers of suitable dielectric constant. The materials are suitable for insulation of high voltage cables, and extend the use of polyethylene insulated cables from voltages of 30 kV to 110 kV, with safety equal to that of known oil or gas pressure cables.

Title: Extracting fats from waste meat products - percolation of solvent forming azeotropic mixture with water dries and extracts fats
IPC: C11B1/10
Filed: 1971-10-08
Abstract: The extraction of fat containing products be means of percolating a solvent through a bed of comminuted materials, whereby for the simultaneously extraction and drying a solvent is used which forms with water an azeotropic mixture with a low boiling point; the material bed is heated to that boiling point and is maintained at that point while vapours are removed; and the percolation is continued until the material temp. has resin above the boiling point of the azetropic mixture. The material bed is pref. preheated and the heat requirement for the evaporation of water is supplied by the circulation of the above the boiling point of mixture preheated solvent, such as perchlorethylene. Complete extraction is obtained in one extractor without any additional equipment.

Title: Automatically pouring molten metal - melt forced by gas pressure from reservoir in which melt level is indirectly determined by weight
Inventor: WICKER HELMUT DIPL-ING
IPC: B22D39/06
Filed: 1973-02-17
Abstract: Melt is held at a predetermined height in a reservoir having a gooseneck outlet just beneath the pouring level in the gooseneck. The melt is supplied by an induction pump and its height determined by weighing the reservoir. A sensor detects the arrival of a mould beneath the gooseneck and raises the gas pressure (via. a controller) pref. abruptly, to commence pouring. An IR detector senses when the mould has been filled and lowers the pressure, pref. abruptly. The filled mould is automatically moved away to be replaced by an empty one.

Patent DE-2362503-A1 (DE)
Title: Transverse conveyor for rolled products - with four independent drives which are coupled together as bar length increases
Inventor: BERZ GERHARD
IPC: B21B39/00
Filed: 1973-12-15
Abstract: The transverse conveyor has a long row of short rolls on which rolled products are fed in their axial direction onto the conveyor; stops which can be raised and lowered are fitted at intervals between the rolls for stopping the bars and the rolls are then lowered so the bars rest on chain conveyors running on xoacial shafts, some shafts being motor-driven. Coupling are used as required to couple the driven shafts to shafts which are not directly driven and, due to this design, the conveyor may be used for the transport of very long bars, in which case all the coaxial shafts are coupled together and driven as one unit; alternatively, for short bar lengths, the conveyor can be operated as four independent units. The conveyor can be adapted to suit a very wide range of bar lengths and can still function even if partial breakdown occurs.
Patent DE-2403553-A1 (DE)
Title: Tape, partic video-type, recording and play-back system - comprises player and cassette with sickle-shaped tape guide
Inventor: THUY HANS-JOACHIM DR RER NAT
IPC: G11B15/62
Filed: 1974-01-25
Abstract: The invention provides a magnetic tape system which is particularly suitable for video recording and playback in that the tape guidance inhibits flutter, without requiring tiresome hand threading of the tape. The tape is held in a cassette which is pushed into a player so that the tape engages against the player head through the action of a sickle-shaped guide. The tape passes from the centre of its spool via a guide between a pressure and drive roller to the guide. From the latter it passes back between the drive roller and another pressure rollers to the outside of the spool, so forming a continuous loop.

Title: Conveyor for vines or other fruit - includes frame with grips for three-point coupling and fixture for buckets
Inventor: SCHWENDEMANN WERNER
IPC: A01D46/24
Filed: 1974-04-18
Abstract: The conveyor has a frame with horizontal arm-shaped extensions on each side in the end of which are holes open at the top in which bucket handles are inserted. The holes are L-shaped, so that the vertical stem of the L is open at the top, and the horizontal part points outwards away from the frame. The bucket sides rest against stop-pieces fixed to the frame; the distance between the abutment surface and the vertical projection of the hanging-holes is less than that between the abutment point on the bucket and the handle of the bucket. The frame is made up of sections, so that those holding the grips for attachment to the three-point coupling are stronger than the other sections. The buckets hang from at least two levels of rail.

Title: Electrosag ingot casting method - cooled ingot reversed through given angle at given reversal rate
Inventor: TUTSCHKEWITSCH NIKOLAI MAXIMOW
IPC: B22D23/10
Filed: 1974-05-04
Abstract: An electro slag melting method for ingot casting, using self consuming electrodes, includes melting the initial half of the charge and rotating it inside a cooled ingot mould in the melting zone between an angle of 5 degrees and 180 degrees at a frequency of reversal between 1 and 30 cycles per minute as crystallisation takes place. This ensures the formation of fine even crystals, thus preventing the occurrence of cavities, piping, shrinkage and similar common casting defects.

Title: Honeycomb ceiling air-ducting and distributing element fixture - with sidewalling of bulkhead-type shaped-section
Inventor: REINARTZ GUENTER
IPC: E04B9/02
Filed: 1974-07-17
Abstract: The honeycomb ceiling is made up from hollow units with bordering side walls on the enclosed bulkhead type, and normally with connecting components which are separate from the air ducting and distributing elements used in ventilation, and tending to impede the action of these. The sidewalling of the element used for this multiple function is wholly or partially of an enclosed bulkhead type with chamber dimensioning corresponding to the interior cross-section dimension of the honeycomb cells, and its main hollow space allotted to the air distributor element, which is thus considerably enlarged, for the improvement of a smooth air flow. The chambers may incorporate honeycomb cell accommodating sections, with notching lugs for the cells.

Title: Auxiliary sewage oxydation plant for levelling out peak loads - part of main feed gasified under pressure and reintroduced
Inventor: ALBRECHT ERHARD ING GRAD
IPC: C02F3/12
Filed: 1974-07-24
Abstract: Oxygen or a gaseous mixt. with a much higher oxygen content than air, is introduced into water or the sewage input of an activated sludge plant, by withdrawing part of the feed flow and subjecting it to a pressure of 2 to 10 atmospheres whilst it is fed through a gasifying vessel in the form of a scrubbing column; or a gas injector may be used. The oxygen or a gaseous micture contg. 40% of oxygen is dissolved in the part flow which is then reintroduced into he main flow, through detenting chokes. Without considerable constructional alteration or expensive stand-by plant, the overloaded purification system or stretch of water can be improved in the shortest time without great loss of oxygen, and the gaseous waste products, esp. CO2, are not put back into the sewage sludge mixture.
